Most of this emitted radiation is at longer wavelengths than solar radiation. Unlike solar radiation, which is mostly at wavelengths visible to the human eye, the Earth's longwave radiation is mostly at infrared wavelengths, which are invisible to the human eye.
The shorter the wavelength, the more energetic the radiation, and the greater the potential for harm. Ultraviolet (UV) radiation that reaches the Earths surface is in wavelengths between 290 and 400 nm (nanometers, or billionths of a meter).This is shorter than wavelengths of visible light, which are 400 to 700 nm.UV-B includes light with wavelengths down to 280 nm, but little to no radiation below 290 nm reaches the Earthâs surface). UV-B causes damage at the molecular level to the fundamental building block of life deoxyribonucleic acid (DNA).
